  2. 1. Unsymmetric PCN Pincer Palladium and Nickel Complexes : Synthesis, Characterization and Reactivity

    Author : Abdelrazek Mousa; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unsymmetric PCN; Palladium; Nickel; Cyclometallation; Carboxylation; Cross-coupling;

    Abstract : New palladium and nickel complexes based on unsymmetric PCN pincer ligands have been synthesized and fully characterized using different techniques. The substituents on the nitrogen side arm of the ligand have great influence on the cyclometallation and the reactivity of the new complexes particularly in case of nickel. READ MORE

  4. 2. Bone and fat tissue in children and adolescents: studies with focus on osteocalcin

    Author : Bojan Tubić; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osteocalcin; obesity; adiponectin; carboxylation; anorexia nervosa; paediatric; bone turnover markers; bone mass; whole body vibration; muscle;

    Abstract : The general AIM was to investigate the possible interplay between bone and fat tissue through clinical studies of children and adolescents. Osteocalcin (OC), a bone formation marker, has been proposed to act as a link between bone and energy metabolism in mice, but human data are inconclusive. READ MORE

  5. 3. Design and Synthesis of 11C-Labelled Compound Libraries for the Molecular Imaging of EGFr, VEGFr-2, AT1 and AT2 Receptors : Transition-Metal Mediated Carbonylations Using [11C]Carbon Monoxide

    Author : Ola Åberg; Bengt Långström; Nicholas Long; Uppsala universitet; []

    Abstract : This work deals with radiochemistry and new approaches to develop novel PET tracers labelled with the radionuclide 11C.Two methods for the synthesis of 11C-labelled acrylamides have been explored. READ MORE

  6. 4. Dispersion Coating for Active Food Packaging: Aroma Interactions and Oxygen Scavenging

    Author : Anna Nestorson; Lars Järnström; Anders Leufvén; Caisa Andersson; José M. Lagaron; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active food packaging; Dispersion coating; Latex; Aroma compounds; Oxygen scavenging; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. READ MORE

  7. 5. Control of fatty acid utilization in brown adipose tissue

    Author : Jan Nedergaard; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In order to keep warm in cold surroundings, mammals have developed a mechanism for non-shivering thermogenesis. The major part of this heat production takes place in brown adipose tissue. The heat results from combustion of fatty acids. READ MORE
